Q: The mentioned effect occurs even when the entire page is completely loaded!
As we explained before, it occurs only when we view the page with explorer 6.
(It is working fine under explorer 7 and under Firefox, so you should check it under explorer 6)
Please see the following link with our test page which demonstrates the problem.
As you will see, the buttons of the javascript menu scroll and the text will disappear (become white) while you move the mouse cursor over the menu buttons. It has nothing to do with page loading.
We are using a "Vista style" javascript menu scroll with custom design pictures.
A: This is IE6 bug.

Q: I’d like to know how to populate the navigation bar menu from a database?
A: Please, see the example of .php file.The content of .php file depends on your database structure.
<?php
// The example for PHP/MySQL.
// MySQL database has the table "menuTable" that contains data for menu items.
// The table has the following fields:
// 1. "text" - item text
// 2. "link" - item link
// 3. "icon1" - item icon (normal state)
// 4. "icon2" - item icon (mouseover state)
function getMenuItems()
{
$jsItems = '';
// Select all records from table "menuTable"
$allItems = mysql_query('SELECT * FROM menuTable;');
// Extract items data from database and build Javascript code for menuItems
while ($itemData=mysql_fetch_array($allItems))
{
$jsItems .= '["'.$itemData['text'].'", "'.$itemData['link'].'", "'.$itemData['icon1'].'", "'.$itemData['icon2'].'"],';
}
// Return Javascript code
return $jsItems;
}
?>
<script>
var menuParam1 = value1;
var menuParam2 = value2;
var menuParam2 = value2;
...
var menuItems = [
// Write Javascript code for menu items
echo getMenuItems();
?>
];
</script>
Q: I have implemented a deluxe-menu on my client's website and I had a couple of questions.
1. Can I control how fast the submenus scroll in my javascript menu examples? If you look at the site and hover over Need An Expert? on the menu and then point to Practice Areas, this submenu seems to scroll slower than if you mouse over "Technology" and scroll that submenu. The Technology submenu scrolls a lot faster. Is it because there are many more items in the Technology submenu? I tried to find a setting for "scroll speed" or the like, but I couldn't find it.
2. In internet explorer, when you mouse over Need An Expert?, Technology the first time you go to the page, there is a 3-4 second delay before the submenu opens. There are a lot of submenu items under Technology, but in Firefox, there doesn't seem to be this delay. Do you know why this would happen in IE? Is there a way to fix it? Could the problem be that each submenu item has a background graphic and this is causing the delay?
3. When you get to a page on the site and you rollover the top level menu, there is also a delay before the background image of the menu items shows up. You get a solid blue background color for a second or two (the bgcolor assigned) and then the graphic loads and shows up. Is there any way around this? I have a javascript to preload the image (back.jpg) but that doesn't seem to help.
Any help would be greatly appreciated!!!
A: 1. The scroll speed depends on number of items to be scrolled, more items -> faster scroll.
You can decrease the number of items or enlarge the size of submenu.
2,3. Please try to add the following param:
var dm_writeAll = 1;
It will load all backgrounds on page load, no on mouseover.
Q: I have one problem you may be able to help with:
If I set
var tsaveState = 1;
The following errors are generated:
_tls is not defined
tob has no properties
and the menu doesn't display.
If you could help with this I would be grateful.
A: You should use dtree_ss.js file.
You should install your menu so:
<noscript><a href="http://deluxe-tree.com">Javascript Tree Menu by Deluxe-Tree.com</a></noscript>
<script type="text/javascript" src="menudir/dtree.js"></script>
<script type="text/javascript" src="menudir/dtree_ss.js"></script>
<script type="text/javascript" src="menudir/tree-data.js"></script>
